Abstract:
اجريت الدراسه الحاليه في معهد الهندسه الوراثيه والتقنيات الاحيائيه - جامعة بغداد خلال الفتره من كانون الثاني ولغاية حزيران - 2013 للكشف عن علاقة بعض الطرز الجين كالبين - 10 بحدوث مرض السكري من النوع الثاني في العراق. تم استخلاص الدنا من الدم الكلي باستخد | The present study was carried out in Genetic Engineering and biotechnology Institute - Baghdad University during a period from January to June, 2013, for detecting the association of some calpain - 10 gene polymorphisms with the incidence of type 2 diabetes mellitus in Iraq. Genomic DNA was isolated by using Geneaid DNA extraction kit from the whole blood; conventional PCR (SNP - 44 and Del/Ins - 19) and PCR - RFLP (SNP - 43 and SNP - 63) were used to detect the calpain10 variants by using specific primers and restriction enzymes. The study population consisted of 50 subjects with type 2 diabetes and 50 with normal fasting blood glucose (80 - 110 mg/dl). The type 2 diabetic subjects were recruited from the National Center for Diabetes treatment and Research. The non - diabetic control subjects were recruited from the same area as the comprising blood donors, healthy volunteers, or hospital /university staff members. Previous studies have detected a role for Calpain - 10 (CAPN10) polymorphisms in susceptibility to Type 2 diabetes mellitus (T2DM) in many populations. This study aimed to evaluate possible associations between these polymorphisms in the CAPN10 gene (SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63) and T2DM incidence in Iraqi population. Enrichment of allele 1(2R) in Del/Ins - 19 and 2R/2R genotype were found in T2DM patients. While the alleles and genotypes distribution of SNP - 44, SNP - 43 and SNP - 63 were not significantly different between patient groups and non - diabetic control subjects. The genotype AA in SNP - 43 and genotype TT in SNP - 63 were not found neither in T2DM nor in control subjects. of the eight haplotypes detected, enrichment of both haplotype 112 defined by variants of SNP - 43, Del/Ins - 19, and SNP - 63 and haplotype 2112 defined by variants of SNP - 44, SNP - 43, Del/Ins - 19, and SNP - 63 were seen in patients. The distribution of the other haplotypes was comparable between patients and control subjects. The calpain10 haplotype combinations were also obtained, and the haplotype combinations 111/111 and 111/112; which are created by variants of SNP - 43, del/ins - 19 and SNP - 63 and; haplotype combinations 1111/2111, 1111/2112 and 1121 / 2222; created by SNP - 44, SNP - 43, del/ins - 19 and SNP - 63; were associated with increasing the risk of T2DM.
